Abstract
An analysis of observations made over a period of a year shows that the phase changes of the signals from NBA as received in Lower Hutt, New Zealand, have a diurnal pattern but with considerable day-to-day and seasonal variations. It is concluded that, as recorded at present, the signal is not sufficiently stable to be used as a reference for standard frequency measurements. A suggestion is made for improving the the reception of the signals for frequency-comparison purposes.Keywords
